What is BigchainDB? — The BigchainDB Blog — Medium

BigchainDB is a blockchain database capable of 1 million writes per second throughput, storing petabytes of data, with sub-second latency, a proper querying system, and rich permissioning. It supports public and private deployments. Being a decentralized database, it is complementary to decentralized processing technologies like Ethereum Virtual Machine, and decentralized file systems like IPFS. It can be used within decentralized computing platforms like Ethereum-Stratos or Eris-Tendermint. This post [1] outlines the need for a scalable blockchain database, provides a high-level description of BigchainDB, presents benchmarks, and concludes with use cases.
